Abstract
A rotational position sensor arrangement having first and second sensors positioned adjacent to first and second axial faces or a first axial face and a radial face of a target disc. The target disc has first and second wave profiles on the first axial face and the second axial or radial face, having respectively, first and second pluralities of segments, with each segment being formed with axially offset peaks and valleys which extend along radial lines/planes. The valleys separate the segments, and the number of the first plurality of segments is different than that of the second plurality of segments. The first and second sensors signal a controller with data on a field variance due to a difference in at least one of a size or location of the first and second wave profiles as they pass the first and second sensors to determine a rotational speed and/or position.
